Description

Blockchain-based design copyright transaction method and system {METHOD AND SYSTEM FOR TRADING COPYRIGHT OF DESIGN BASED ON BLOCKCHAIN}

The following embodiments relate to a method and system for trading copyrights of designs based on a block chain, and more specifically, to provide services for registering and selling copyrights of digital contents including designs, and to provide service rewards to creators and users with copyrights. It is about a block chain-based design copyright transaction method and system that pays

Since digital data can be easily reproduced, it is difficult to distinguish between an original copy and a copy, so it is difficult to guarantee data originality. With the recent emergence of NFT (Non-Fungible Token), the original can be distinguished or protected.

NFT refers to certain non-fungible cryptographic digital assets issued by Ethereum. By storing ownership of digital files on a blockchain, it is possible to preserve them permanently by making them impossible to forge or tamper with. By enabling the ownership of digital assets to be confirmed in a decentralized form, even if there are 1 million identical digital photos, it is possible to identify the original of the first registered photo.

Digital contents for visual art works can be traded in a marketplace where NFTs can be traded (eg, opensea). For example, creators can safely register, sell, and manage digital content copyrights.

On the other hand, a coloring book is a picture book in which a user completes a drawing by coloring an outline drawing, and it is emerging as a healing item in that it can spend time without thinking about anything. The materials of the sketches are diverse, such as geometric patterns, figures, animals, and mandalas. Coloring designs drawn by illustrators can play an optimal role as sketches for coloring books because of the beauty and uniqueness of the patterns. Accordingly, along with the increasing interest in coloring books, illustrators' interest in the coloring book market is also increasing. However, since the conventional coloring book is a physical paper on which coloring designs are printed, there is a disadvantage in that it is inconvenient in terms of portability. In order to solve these disadvantages, coloring services providing coloring books through smart phone applications are increasing.

The designs provided in the coloring book through these smartphone applications also require copyright protection or transaction and management of the creators.

Hereinafter, a specific embodiment of a block chain-based design copyright transaction method and system that provides services for registering, selling, and managing copyrights of digital contents, including designs, and provides service rewards to users with copyrights, including creators. will explain

Figure 3 is a block diagram showing a copyright transaction system of a block chain-based design that can be included in a processor of a server according to an embodiment, Figure 4 is a copyright transaction of a design that can be performed by a server according to an embodiment Here is a flow chart showing the method.

Referring to Figures 3 and 4, the server 150 according to one embodiment may be configured with a computer-implemented design copyright transaction system. The server 150 provides a design copyright transaction service for a plurality of electronic devices 110, 120, 130, and 140 that are clients, and the electronic devices 110, 120, 130, and 140 In response to a service request through a dedicated application installed on the server 150 or access to a web/mobile site related to the server 150, the design copyright transaction service is provided and the reward is paid to the user and/or the creator of the coloring design Copyright of the design transaction method can be performed.

In more detail, the server 150 displays at least one coloring pattern on the user's electronic device (eg, the first electronic device 110) and provides a coloring tool so that the user can color the at least one coloring pattern. Rewards can be paid to users and creators (illustrator who produced and provided at least one coloring design).

Hereinafter, the plurality of electronic devices 110, 120, 130, and 140 are described as a plurality of terminals 110, 120, 130, and 140, and the user's electronic device is described as the user's terminal.

A blockchain-based design copyright transaction system may be provided so that the server 150 can perform the design copyright transaction method according to FIG. 4 . More specifically, the processor 222 of the server 150 may include a coloring design management unit 310, a coloring design sales unit 320, and a reward payment unit 330 as shown in FIG. 3 as components. . Depending on embodiments, components of the processor 222 may be selectively included in or excluded from the processor 222 . Also, components of the processor 222 may be separated or merged to express functions of the processor 222 according to embodiments. For example, at least some of the elements of the processor 222 may be implemented in a processor included in a user's terminal.

The processor 222 and components of the processor 222 may control the server 150 to perform steps S410 to S450 included in the copyright transaction method of FIG. 4 . For example, the processor 222 and components of the processor 222 may be implemented to execute instructions according to an operating system code included in the memory 221 and at least one program code.

Here, components of the processor 222 may be representations of different functions of the processor 222 performed by the processor 222 according to instructions provided by program codes stored in the server 150. . For example, as a functional expression of the processor 222 that controls the server 150 according to the above-described command so that the server 150 provides at least one coloring pattern and information on the coloring pattern to the user's terminal, a coloring pattern management unit. (310) may be used.

The processor 222 may read necessary commands from the memory 221 loaded with commands related to the control of the server 150 before step S410 (not shown as a separate step in the drawing). In this case, the read command may include a command for controlling the processor 222 to execute steps S410 to S450 to be described later.

First, the wallet generator (not shown) creates a wallet for trading of coloring patterns through a user's terminal. After the wallet is created, a coloring design is provided from the creator, and a reward can be paid when the copyright of the coloring design is sold.

In step S410, the coloring pattern management unit 310 receives at least one coloring pattern from at least one or more creators. Here, the coloring design may be a design drawn as a sketch that can be colored or additionally drawn. The provided coloring pattern is stored and maintained in the memory 221, so that it can be used in a step to be described later. Hereinafter, at least one creator means an artist who produced a plurality of coloring designs.

In step S420, the coloring pattern management unit 310 displays the coloring pattern or information on the coloring pattern on the user's terminal. For example, the coloring pattern manager 310 may extract the coloring pattern stored and maintained in the memory 221 and then provide the coloring pattern or information on the coloring pattern to the user's terminal. For example, the coloring pattern may be provided in a thumbnail format, but is not limited or limited thereto, and the drawing may be presented as it is or text related to the drawing may be provided.

The coloring pattern management unit 310 may display at least one or more coloring patterns selected by the user from among the coloring patterns on the user's terminal. For example, the coloring pattern management unit 310 recognizes at least one or more coloring patterns selected from among a plurality of coloring patterns according to a user's selection input generated on a list of coloring patterns provided to the user's terminal, and then selects at least one or more coloring patterns. The coloring pattern may be displayed on the user's terminal. Here, displaying the selected at least one coloring pattern on the user's terminal may mean displaying the selected at least one or more coloring pattern on the entire screen of the user's terminal.

Although not shown in the figure, prior to step S420, the coloring pattern management unit 310, as at least one coloring pattern is selected from among a plurality of coloring patterns by the user, the user pays for using the copyright transaction service of the pattern (cost ) can be paid. Here, the price for the user to use the copyright transaction service of the design may be paid by the user in blockchain-based cryptocurrency, but is not limited or limited thereto.

In step S430, the coloring pattern sales unit 320 sells the copyright of the registered coloring pattern as the creator or the user who has the copyright of the coloring pattern decides to sell. For example, the coloring design sales unit 320 may sell the copyright of the registered coloring design as the creator decides to sell it.

Meanwhile, a user who has purchased a copyright of a coloring pattern may be a user having a copyright of the coloring pattern. In this case, the coloring pattern sales unit 320 may resell the copyright of the registered coloring pattern as the user who has the copyright of the coloring pattern determines to sell.

According to the embodiment, the blockchain-based design copyright transaction system may further include a reward payment unit 330 .

In step S440, the reward payment unit 330 receives a cost (price) from the user who purchases the copyright of the coloring pattern when selling the copyright of the coloring pattern. Here, the cost may be paid in blockchain-based cryptocurrency, but is not limited thereto. For example, expenses can be paid in tokens, points, etc.

In step (S450), the reward payment unit 330 pays a preset reward to the creator and the user who has the copyright of the coloring design.

Here, the reward payment unit 330, when the creator and the user having the copyright of the coloring design match, can pay the creator a fee excluding fees. In addition, the reward payment unit 330, when the creator and the user who has the copyright of the coloring design do not match, pays the creator a preset reward among the costs excluding the fee, and after excluding the preset reward from the cost excluding the fee The remaining cost can be paid to the user who has the copyright of the coloring design.

In particular, the reward payment unit 330 may pay a reward in blockchain-based cryptocurrency. Here, in the block chain that is the basis of the cryptocurrency, record information in which at least one creator provided at least one coloring pattern, at least one coloring pattern selected by a user, and at least one coloring pattern sold to the user. Record information, record information in which at least one coloring pattern is colored or drawn by a user, record information in which a reward is paid to at least one creator in relation to at least one coloring pattern, and the like may be stored.

In this way, the copyright transaction system of the design pays rewards in blockchain-based cryptocurrency, and stores and maintains all information related to the provision of the copyright transaction service of the design in the block chain, improving data security and trading the copyright of the design. It can have the advantage of easy service management, satisfy at least one creator more than if the reward is paid in tokens, and improve the convenience of the copyright transaction service provider of the design than if it is paid in cash.

Here, the reward paid to at least one or more creators may be determined according to various conditions. For example, the reward payment unit 330 is to pay to at least one creator based on at least one of the posting period of at least one coloring design, popularity, user provided number, user coloring authority, user coloring range, or user coloring difficulty. By determining the amount of reward, the determined amount of reward may be paid to at least one creator.

In addition, as described above, the reward paid to one or more creators may be at least a part of the price paid by the user when the user selects one or more coloring designs. For example, as the coloring pattern management unit 310 selects at least one coloring pattern among a plurality of coloring patterns by the user, after the user is paid for using the copyright transaction service of the pattern, the reward payment unit 330 may pay at least a portion of the consideration to at least one creator.

5 is a diagram for explaining a method of providing a reward when a creator sells a copyright of a coloring design for the first time according to an embodiment, and FIG. 6 is a diagram for a user who has a copyright of a coloring design according to an embodiment to It is a diagram for explaining a method of providing a reward in the case of selling.

Referring to FIG. 5, for example, when the creator 510 sells the copyright of the coloring design for the first time, the server 530 gives the creator 510 100% of the sales amount received from the buyer 520 excluding commissions, etc. Profits can be paid as rewards. At this time, the token 540 may be used for a transaction.

Referring to FIG. 6, for example, when a user 620 who has purchased a copyright of a coloring design from a creator 610 sells the copyright of a coloring design secondary, the creator 610 receives a sale from the purchaser 650. A profit of a predetermined percentage (eg, 10%) may be paid out of the amount. In addition, the user 620 who has purchased the copyright of the coloring pattern may receive compensation for the copyright of the coloring pattern. At this time, the token 640 can be used for a transaction.

In other words, by giving the copyright of the coloring design to the creator and giving ownership of the coloring design to the user who has the copyright of the coloring design, at least a part of the copyright of the coloring design can be given to the creator whenever a sale is made. That is, when a user holding a copyright of a coloring design sells a copyright of a coloring design, a predetermined percentage of profit may be allocated to the creator.

Meanwhile, the coloring pattern management unit 310 may display a secondly generated work using the coloring pattern on the user's terminal.

Here, the secondly created work may mean a work created by a user coloring or additionally drawing using a coloring design. For example, when a user completes coloring using a coloring tool, the coloring pattern management unit 310 may provide an opportunity to edit or expose at least one colored coloring pattern to other users. Here, the editing may include a function of giving a special effect to at least one or more colored coloring patterns, a function of changing the texture of at least one or more coloring patterns, a function of applying a filter to at least one or more coloring patterns, or a function of attaching an emoticon. can Exposing at least one colored coloring pattern to other users means sharing the at least one colored coloring pattern with other users through a mobile messenger, e-mail, SNS, text message, site upload, or the like.

In this way, the value or popularity of the creator's coloring pattern can be increased by sharing the secondly generated work representing an example that can be utilized using the creator's coloring scheme with other users.

Accordingly, the reward payment unit 330 may additionally provide a predetermined reward to a user of a secondly generated work using the coloring pattern when selling the copyright of the coloring pattern. At this time, a predetermined reward may be given to all users of the secondly created work, and a predetermined reward may be selectively paid according to preset criteria such as popularity among users of the secondly created work. there is.

In this way, the copyright transaction method of the design according to one embodiment, in providing the copyright transaction service of the design to the user, by paying a reward to the creator who produced and provided the coloring design used in the copyright transaction service of the design, many creators In addition, it is possible to increase the influx of users by securing a large amount of high-quality color designs according to the influx of many creators.

In the above, the copyright transaction method of a design for paying a reward to one or more creators has been described, but a reward may also be paid to a user receiving a copyright transaction service of a design in a similar manner.

Below, registration and sales of coloring designs will be described by taking opensea, one of the marketplaces for trading, as an example.

Non-Fungible Tokens (NFTs) play an important role in resolving ownership disputes of digital assets. Recently, NFTs play an important role in recognizing the independent value of digital assets.

The key elements of NFT are ERC-20 and ERC-721. ERC stands for ‘Ethereum Request for Comment’, which refers to the protocol that must be followed when creating tokens on the Ethereum network. ERC-20 is a cryptocurrency produced according to the 20th protocol. It can be exchanged with ETH and other currencies based on ERC-20, so it can be freely sent through a wallet that supports the token. ERC-721 is a token that introduces the concept of non-fungible NFT in the network. Here, the difference between ERC-20 and ERC-721 is that ERC-20 is replaceable, whereas ERC-721 has unique values of non-replaceable features.

For example, Cryptokitties are made up of ERC-721 tokens to become the only cat in the world that can be exchanged for other tokens.

These NFTs play a role in ensuring ownership of digital assets. However, NFTs have scalability and excessive cost issues.

Meanwhile, Klaytn uses KIP-7 and KIP-17 as token standards. Like ERC-20 and ERC-721, KIP-7 and KIP-17 have either replaceable or non-replaceable features, respectively. KIP-7 and KIP-17 are optimized for Klaytn and thus more suitable for use in the ecosystem. This means that Klaytn supports ERC-20 and ERC-721, but ERC-20 and ERC-721 may not be compatible with tools in the Klaytn ecosystem.

For trading, coloring designs can be registered on marketplaces, such as opensea. More specifically, it is possible to create a wallet, for example, Metamask, and register a coloring pattern in the opensea server. And it is possible to register the sale of the initial coloring design. At this time, an initial cost may be incurred when registering an initial coloring pattern, and no cost is incurred when registering a coloring pattern later.

7 is a diagram showing an example of creating a Metamask wallet according to an embodiment.

For example, the metamask wallet creation process can proceed as follows. To create an initial metamask wallet, you can create a wallet password and check the provided security code. Referring to FIG. 7 , upon completion of wallet generation (address value generation), the corresponding wallet (address value) can be connected to opensea.

In order to initiate a coloring design on opensea, the creator can upload the coloring design to the server through the user's terminal. For example, an item can be created in a folder (an item actually sold), and detailed settings of the item can be set. When the upload of the coloring pattern is completed, the chain information/contract address and ID, blockchain for the coloring pattern are configured, and the chain information of the coloring pattern can be provided.

In order to sell the copyright of the coloring design to opensea, the coloring design is uploaded, and the chain information/contract address, ID, and blockchain for the coloring design can be configured. Here, gas cost is required for initial opening in the upload window, and gas cost is not required thereafter.

On the other hand, if the copyright of the coloring design is not sold after the coloring design is uploaded to open sea, it is not shared with others. If the copyright of the coloring design is not sold, 'status on hold' may appear in the detailed information. In this case, it is necessary to check whether the copyright of the coloring design has been certified. At this time, there is no need to create a separate account within opensea, and there is no need to check the flow of issuing tokens in Ethereum. When canceling the copyright of a coloring design after selling it, gas costs are required.
